The more I think about it, the more I realize that she's easily Nolan's worst written villain. She had zero redeeming qualities.

We don't know if Ra's was genuine in his fondness for Bruce or if that was all a form of manipulation on his part but we definitely felt something when he and Bruce were at odds in the end. Bane might've blown people to pieces but his past with Talia humanize him. Two-Face was obviously sympathetic. The Joker and Scarecrow were just fun in general. Talia was none of that. She wasn't even remotely interesting when she was Tate.
